Learjet Observatory
An airborne observatory is an airplane or airship with an astronomical telescope. By carrying the telescope to a sufficiently high altitude, the telescope can avoid cloud cover, pollution, and carry out Observational astronomy, observations in the infrared spectrum, above water vapor in the atmosphere which water absorption, absorbs infrared radiation. Some drawbacks to this approach are the instability of the lifting platform, the weight restrictions on the instrument, the need to safely recover the gear afterward, and the cost compared to a comparable ground-based observatory. Multiple observations of solar eclipses were performed from 1920 to 1980. NASA created first specialised airborne observatory, Galileo, in 1965. SOFIA, the latest such observatory, was retired in 2022. History Eclipse chasing Early attempts First attempts to observe astronomical objects from planes were made in 1920 from a biplanes. Until 1960, the main objects of such observations were solar eclipses. ...

Solar Eclipse Of January 24, 1925
A total solar eclipse occurred at the Moon's descending node of orbit on Saturday, January 24, 1925, with a magnitude of 1.0304. A solar eclipse occurs when the Moon passes between Earth and the Sun, thereby totally or partly obscuring the image of the Sun for a viewer on Earth. A total solar eclipse occurs when the Moon's apparent diameter is larger than the Sun's, blocking all direct sunlight, turning day into darkness. Totality occurs in a narrow path across Earth's surface, with the partial solar eclipse visible over a surrounding region thousands of kilometres wide. Occurring about 1.1 days after perigee (on January 23, 1925, at 13:30 UTC), the Moon's apparent diameter was larger. Totality was visible from southwestern and southeastern Ontario in Canada (including Toronto and Niagara Falls), Minnesota, Wisconsin, Michigan, Pennsylvania, New York (including the northern part of New York City), New Jersey, Connecticut, Rhode Island, and Massachusetts. A partial eclipse was vis ...

Later, the magazine became outspoken on environmental issues. Until 2015, the magazine was completely owned and managed by the National Geographic Society. Since 2015, controlling interest has been held by National Geographic Partners. Topics of features generally concern geography, history, nature, science, and world culture. The magazine is well known for its distinctive appearance: a ...

United States Army Air Corps
The United States Army Air Corps (USAAC) was the aerial warfare service component of the United States Army between 1926 and 1941. After World War I, as early aviation became an increasingly important part of modern warfare, a philosophical rift developed between more traditional ground-based army personnel and those who felt that aircraft were being underutilized and that air operations were being stifled for political reasons unrelated to their effectiveness. The USAAC was renamed from the earlier United States Army Air Service on 2 July 1926, and was part of the larger United States Army. The Air Corps became the United States Army Air Forces (USAAF) on 20 June 1941, giving it greater autonomy from the Army's middle-level command structure. During World War II, although not an administrative echelon, the Air Corps (AC) remained as one of the combat arms of the Army until 1947, when it was legally abolished by legislation establishing the United States Department of the Air Fo ...

Vought O2U Corsair
The Vought O2U Corsair is a 1920s biplane scout and observation aircraft. Developed by Vought Corporation, the O2U was ordered by the United States Navy (USN) in 1927. Powered by a 400 hp (298 kW) Pratt & Whitney R-1340 engine, it incorporated a steel-tube fuselage structure and a wood wing structure with fabric covering. Many were seaplanes or amphibians. The O2U was the first of several Vought planes to bear the name Corsair. The Vought SBU Corsair of 1933, Vought F4U Corsair of 1938, and A-7 Corsair II of 1963 all also bore the name. Design and development Two prototypes were ordered in 1926 and tested by the Navy Trial Board before the first production batches were ordered. In 1927, a total of 291 O2Us were produced. The O2U-2, -3 and -4 were ordered in 1928 with minor changes. By 1930 they were being superseded by the O3U which was basically similar to the O2U-4, one variant of which was fitted with the Grumman Float (nautical), float, and were manufactured unt ...

Honey Lake
Honey Lake is an endorheic basin, endorheic sink (geography), sink in the Honey Lake Valley in northeastern California, near the Nevada border. Summer evaporation reduces the lake to a lower level of and creates an alkali flat. Honey Lake dries almost completely in most years. Honey Lake recreational activities include bird watching, picnicking, hiking, camping, warm-water fishing, and waterfowl hunting. The lake is part of the Honey–Eagle Lake (Lassen County), Eagle Lakes watershed of which includes the Honey Lake Basin of . History The lake received its name from the Honeydew (secretion), honeydew produced by the abundant aphids inhabiting the area. During the Pleistocene, Honey Lake and the entire Honey Lake Valley were part of Lake Lahontan in western Nevada, with a lake water level of a level of approximately higher than the 1984 level of Honey Lake.''Susanville, California,'' 30x60 Minute Topographic Quadrangle, USGS, 1984 The connection to Lake Lahontan was throug ...
